O le EDFA (Erbium-doped Fiber Amplifier), na muamua faia i le 1987 mo le faʻaaogaina faapisinisi, o le faʻapipiʻi faʻapipiʻi sili ona faʻapipiʻiina i le DWDM system lea e faʻaogaina ai le fiber Erbium-doped e pei o le faʻapipiʻi faʻapipiʻi faʻapipiʻi e faʻaleleia saʻo ai faailoilo.E mafai ai ona fa'ateleina fa'avave mo fa'ailo e tele galu umi, fa'atatau i totonu o fusi e lua.O le tasi o le Faiga masani, poʻo le C-band, pe a ma le 1525 nm i le 1565 nm, ma le isi o le Long, poʻo le L-band, pe a ma le 1570 nm i le 1610 nm.I le taimi nei, e lua e masani ona faʻaaogaina pamu pamu, 980 nm ma 1480 nm.O le 980nm band e maualuga atu le absorption cross-section e masani ona faʻaaogaina i le maualalo o le pisa, ae o le 1480nm band o loʻo i ai se laʻititi laʻititi ae sili atu le lautele o le absorption cross-section lea e masani ona faʻaaogaina mo le maualuga o le eletise.
O le ata o lo'o i lalo o lo'o fa'amatala manino mai ai le fa'asiliina o fa'ailoga e le amplifier EDFA.A galue le EDFA amplifier, e ofoina atu le laser pamu ma le 980 nm poʻo le 1480 nm.O le taimi lava e pasi atu ai le laser pamu ma faʻailoga faʻapipiʻi i totonu o le mea faʻapipiʻi, o le a faʻapipiʻiina i luga o le fiber Erbium-doped.E ala i le fegalegaleai ma le doping ions, e mafai ona ausia mulimuli ane le faʻalauteleina o faʻailoga.O lenei mea fa'apipi'i fa'apitoa uma e le gata ina fa'aitiitia ai le tau ae fa'aleleia atili ai le lelei mo le fa'alauteleina o fa'ailoga.I se faapuupuuga, o le EDFA amplifier o se mea taua i le tala faasolopito o fiber optics e mafai ona faʻalauteleina faʻailoga ma le tele o galu i luga o le tasi fiber, nai lo le faʻapipiʻiina o faʻailoga eletise-eletise-optical.
Rofea Optoelectronics o loʻo ofoina atu se laina oloa o faʻatauga eletise eletise-optic modulators, vaega modulators, photodetectors, puna malamalama laser, lasers dfb, faʻamalosi mata, EDFAs, leisa SLD, QPSK modulation, laser pulse, malamalama malamalama, photodetector paleni, Semiconductor laser, avetaavale laser. ,fibre coupler, leisa fa'amalo, fa'alava fa'alava fa'atele, mita eletise mata, leisa broadband, leisa Tunable, fa'atuai fa'ateteleelekta fa'ata'ita'i, fa'amatalaga mata, Aveta'avale diode laser, fa'alava fibre, erbium doped fiber amplifier, fa'apogai moli, laser puna malamalama.Matou te tuʻuina atu foʻi le tele o modulators faʻapitoa mo aganuʻu, e pei o le 1 * 4 array phase modulators, ultra-low Vpi, ma le ultra-high extinction ratio modulators, faʻaaoga muamua i iunivesite ma inisitituti. eletise-optic bandwidths e oʻo atu i le 40 GHz faʻatasi ma le faʻaofiina maualalo gau, maualalo Vp, maualuga PER.E talafeagai mo le tele o talosaga mai analog RF so'oga i feso'ota'iga televave.
